A voussoir is a wedge-shaped element in an arch, a mason's term borrowed in Middle English from French verbs connoting a "turn" (OED). Each wedge-shaped voussoir turns aside the thrust of the mass above, transferring it from stone to stone to the final edge, which is horizontal and passes the thrust to the supports. Voussoir arches distribute weight efficiently and take maximum advantage of the compressive strength of stone, as in an arch bridge.
